I have had the Marino, then Echo Pure, then Sky 2, then ZHI team, then Onza Limey 4, then Sky 2, then Monty Kamel 231. So, you were not that far hahahahaha
The price was around 300 euros or I remember well and and I just asked him to make a triple seat tube! But I don't know if that is what you want to know so ask me.
Oh well seeing the way my Monty rides, I have to agree that BB is too high. But shorter wheelbase (around 1085) is awesome with that BB height and a very long stem and low angle.
That was great, how can you be so smooth, all that seemes so easy. It kinds of reminds me when I started trials with a mountain bike. Except I couldn't do what you do here. Seriously well done, almost makes me want to build a Ryan Leech kind of trials bike.
There is way to make an ultra light comp trials bike for your kid. Just wait for the new Try-All K2 mod rims to be out, add some Monty tires, full titanium hardware, light random parts and you should be below 7 easy peasy
